4G mobile communications networks are increasingly vulnerable to cyber intrusion, according to a new report from a Federal Communication Commission advisory group.
The attack vector, which targets the Diameter signaling protocol used to move traffic on 4G networks, hasn’t been successfully exploited yet, according to Travis Russell, chair of the FCC’s Communications Security, Reliability and Interoperability Council’s working group on network reliability and security risk reduction. But he said mobile phones and the networks that support them are drawing increasing attention from bad actors.
